-# `tsidp` - Tailscale OpenID Connect (OIDC) Identity Provider
-
-[![status: experimental](https://img.shields.io/badge/status-experimental-blue)](https://tailscale.com/kb/1167/release-stages/#experimental)
-
-`tsidp` is an OIDC Identity Provider (IdP) server that integrates with your Tailscale network. It allows you to use Tailscale identities for authentication in applications that support OpenID Connect, enabling single sign-on (SSO) capabilities within your tailnet.
-
-## Prerequisites
-
-- A Tailscale network (tailnet) with magicDNS and HTTPS enabled
-- A Tailscale authentication key from your tailnet
-- Docker installed on your system
-
-## Installation using Docker
-
-1. **Build the Docker Image**
-
-   The Dockerfile uses a multi-stage build process to:
-   - Build the `tsidp` binary from source
-   - Create a minimal Alpine-based image with just the necessary components
-
-   ```bash
-   # Clone the Tailscale repository
-   git clone https://github.com/tailscale/tailscale.git
-   cd tailscale
-   ```
-
-   ```bash
-   # Build the Docker image
-   docker build -t tsidp:latest -f cmd/tsidp/Dockerfile .
-   ```
-
-2. **Run the Container**
-
-   Replace `YOUR_TAILSCALE_AUTHKEY` with your Tailscale authentication key.
-
-   ```bash
-   docker run -d \
-     --name `tsidp` \
-     -p 443:443 \
-     -e TS_AUTHKEY=YOUR_TAILSCALE_AUTHKEY \
-     -e TS_HOSTNAME=tsidp \
-     -v tsidp-data:/var/lib/tsidp \
-     tsidp:latest
-   ```
-
-3. **Verify Installation**
-   ```bash
-   docker logs tsidp
-   ```
-
-   Visit `https://tsidp.tailnet.ts.net` to confirm the service is running.
-
-## Usage Example: Proxmox Integration
-
-Here's how to configure Proxmox to use `tsidp` for authentication:
-
-1. In Proxmox, navigate to Datacenter > Realms > Add OpenID Connect Server
-
-2. Configure the following settings:
-   - Issuer URL: `https://idp.velociraptor.ts.net`
-   - Realm: `tailscale` (or your preferred name)
-   - Client ID: `unused`
-   - Client Key: `unused`
-   - Default: `true`
-   - Autocreate users: `true`
-   - Username claim: `email`
-
-3. Set up user permissions:
-   - Go to Datacenter > Permissions > Groups
-   - Create a new group (e.g., "tsadmins")
-   - Click Permissions in the sidebar
-   - Add Group Permission
-   - Set Path to `/` for full admin access or scope as needed
-   - Set the group and role
-   - Add Tailscale-authenticated users to the group
-
-## Configuration Options
-
-The `tsidp` server supports several command-line flags:
-
-- `--verbose`: Enable verbose logging
-- `--port`: Port to listen on (default: 443)
-- `--local-port`: Allow requests from localhost
-- `--use-local-tailscaled`: Use local tailscaled instead of tsnet
-- `--dir`: tsnet state directory
-
-## Environment Variables
-
-- `TS_AUTHKEY`: Your Tailscale authentication key (required)
-- `TS_HOSTNAME`: Hostname for the `tsidp` server (default: "idp")
-- `TS_STATE_DIR`: State directory (default: "/var/lib/tsidp")
-- `TAILSCALE_USE_WIP_CODE`: Enable work-in-progress code (default: "1")
-
-## Support
-
-This is an [experimental](https://tailscale.com/kb/1167/release-stages#experimental), work in progress feature. For issues or questions, file issues on the [GitHub repository](https://github.com/tailscale/tailscale)
